Rooting the Android operating system is all about becoming the root user, so you can choose what goes on the device and what is taken off the device. The root user account is blocked so that it is hidden to give everyone around the world the ultimate security package which makes lots of sense given that most people have no idea what they are doing online. That does not mean that Google hopes anybody ever roots the Android operating system—we know that developers need to have root access no matter what. All it means is that for people to become the root user the yare going to have to do a bit of work to get there, and that is what we exist for (to help get you there).

For the most part, rooting is going to mean you can install more apps and remove apps that are already on the device. The apps that we call stock apps have another name which is system apps. That is because they are installed on the system partition and the reason they are installed on the system partition is that manufacturers and phone carrier networks know that we cannot get anything off the system partition unless we have root access—something no device comes with out of the box.

What Is Rooting the Android Operating System?

When you buy a new smartphone, you might not know it, but the Android operating system is in a “locked” state. For the most part, it will not make much difference to you: most apps are still available to use, and there are benefits to this locked state such as better security. When you root the Android operating system, you are gaining full administrative rights over the OS.

Why Would You Want to Root Android?

Gaining full administrative rights over the operating system has some perks to some people. For example, out of the millions of applications available on Google Play, some of them will not be able to run on your device unless it has root access. Until you have a specific need for wanting Android rooted, you probably want to leave Android as it comes out of the box. But if you need to unlock an app, then that is when you want to look into rooting methods. Using more apps is only one example of why you may want root access, here is the full list of benefits:

  • Unlock more applications. Some of the apps available for Android cannot run unless you have root access. This is because the app’s features cannot run without the root permissions because the features require the full system access before they can be useful.
  • Better battery life. Smartphones are great, but they have one caveat, which is each time you recharge the battery, it loses some of its overall lifespan. That means smartphones, in general, do not make great investments, and if your weekly paycheck is low, you will want to limit the number of smartphones you go through. One of the ways you can do that is by removing bloatware and creating a better battery life.
  • Bolster performance. If you are the budget-conscious shopper, you may want to increase the device’s performance. This can be done by removing the bloatware as well. The more processes you have running, the more memory that is used. By removing some of the apps, it can help lighten the load on your hardware.
  • Customize Android with themes. With root access, you can download and install any theme that’s at your disposal. That includes any customized theme you can find.

What Are the Risks of Rooting?

If you are buying a smartphone that is not running iOS, then it is probably the Android operating system that you want running as the ideal software to pair with your shiny new hardware. It is, in fact, the Android OS that offers you the chance to customize the OS considerably more than iOS: custom themes, run any app you know about, the works. For many users, the “openness” of an operating system is important, because it offers them more freedom which means running into fewer problems with their investments. But there is a reason iOS likes a far more locked approach: the ability to customize is not for everyone, and if you do not know what you are doing it can lead to a lot of problems which can define your time with the OS rather than freedom.

With power (full admin permissions) comes greater responsibility. Here are some of the main risk factors when it comes to rooting:

  • Malware becomes a larger threat. You might read the occasional news article about how new malware is wreaking havoc in parts of the world on Android. But the Android operating system with root access becomes considerably more vulnerable to exploits because applications are no longer prisoned off in their own sandbox environments. This means if you accidentally download malware, it can do more damage because it can spread throughout the operating system and even jump into other applications and potentially view sensitive data.
  • You can accidentally brick the smartphone. There is always a chance that you end up bricking the smartphone before you had the opportunity to use it with root access. That is because if you are going to brick it, it is going to happen during the rooting process.
  • You may void the warranty. Most manufacturers do not allow you to root the Android operating system and still get to bring it in for repairs under warranty. Whether they are legally meant to do that or not is another question, but it is now common knowledge that most do not want to help you if they find out you have unlocked the OS with root access.

Details We Should Know

  • Chainfire was running on the LRX22G.P905XXUABOK3 firmware build number when he created the rooting method that is available in this guide. He does not mean that you need to be running on the same firmware build number is him when he gives this information to us from the repository. All it means is that the information is there for you to use it as a guideline for the time the rooting method was made because some of the Samsung devices do not boot old images. All you need to have is the Samsung Galaxy Note Pro tablet that comes with the SM-P905 model number and have it running on the Android 5.0.2 Lollipop software updates, and this guide should work for you.
  • The reason the guide should work for all Android 5.0.2 Lollipop updates is that new Android versions are what brings new bootloaders and only the new bootloader cause the CF-Auto-Root tool to go down temporarily until Chainfire updates the files. You can let Chainfire know that a rooting method is not working by leaving a message with the recovery image file found in the firmware you are running on the CF-Auto-Root tool thread made over at the XDA-Developers website. He sees your messages and uses the new recovery images files to update the CF-Auto-Root tool so that it starts working again.

Files We Need

  • Download the CF-Auto-Root file for the Samsung Galaxy Note Pro 12.2 SM-P905 device running on the Android 5.0.2 Lollipop software updates.
  • Download the Samsung USB Drivers for the Windows computer.

Rooting the Samsung Galaxy Note Pro 12.2 SM-P905 running on the Android 5.0.2 Lollipop software updates

  1. Start off by logging into the Windows computer using the administrator’s account so that the Odin flashing tool allows you to flash the files.
  2. Unlock the Developer Options menu on the Samsung Galaxy Note Pro if you have not got it unlocked already.
  3. Enable the USB Debugging Mode on the Samsung Galaxy Note Pro device from within the Developer Options menu that you just unlocked so you can make changes to the Android software.
  4. Extract the rooting file in the Downloads folder on the computer—the default downloads location for your files on a Windows PC and where the rooting file has ended up after you downloaded it.
  5. Install the Samsung USB Drivers on the computer so the Galaxy Note Pro can be detected by the Odin flashing tool.
  6. Open the Downloads folder on the computer and double-click on the Odin flashing tool file.
  7. Boot the Samsung Galaxy Note Pro mobile device into the download mode and then connect it to the computer with the USB cable.
  8. Click on the AP button and then browse through to the Downloads folder and select the rooting MD5 file to upload to the AP button in Odin.
  9. Click on the Start button and the rooting of the Samsung Galaxy Note Pro 12.2 begins.
  10. Check out the text that is programmed to roll down the mobile devices display which is there to let you know what is happening to the device.
  11. Wait until the Odin user interface shows a green pass message in a box before unplugging the device from the computer.

In conclusion, that is everything you need to root the Samsung Galaxy Note Pro 12.2 SM-P905 running on the Android 5.0.2 Lollipop software updates by flashing the CF-Auto-Root tool by Chainfire. The guide has just had the SuperSU installed and enabled on the device, and you can see it available from the app drawer when it reboots. You can open the SuperSU app and take a look at the options available inside, so you do not need to do anything to the options before you start installing the root applications. They work as soon as you download them because the SuperSU sends you a message and ask if you would like to grant the app root access or not. You do not get messages from apps that do not require root access before they can run. You do get messages each time you install an app like Titanium Backup that cannot run without the rooting permissions over the Android operating system.

Rooting the Android OS that is running on the Samsung Galaxy Note Pro device is about what you can install and what you can uninstall. That almost always means what apps you can install and uninstall. The Google Play Store hosts most of these apps that need root access before they can run, but Google Play does do not have an area where you check out the names of the apps that you need to install. What you need to do is already have the names of the root applications with you and the search for them. You can check out some of them from our list of what we think are the best root apps for the Android operating system that is running on your Samsung Galaxy Note Pro device and remember the names.
